I analyse how the inclusion of working condition data influences the estimated marginal effects of student demographics on teacher mobility. Using detailed administrative data on public schools, combined with unique data describing teachers’ perceptions of working conditions, I estimate a model characterizing the multinomial outcomes of teachers choosing to work at different schools. By comparing the estimated marginal effects of student characteristics with and without incorporating detailed working conditions, I find that excluding these additional data results in overestimating the effect of student characteristics on the probability a teacher moves to a different school, but has no influence on estimated effects for the probability of leaving teaching altogether.  相似文献

We examine the determinants of occupational earnings of UK 1993 graduates and focus on the influence of the type of school the graduate attended prior to university entrance. For data reasons, we restrict attention to graduates who attended school in England. We estimate that, on average, a male (female) graduate who attended an Independent school receives an earnings premium of 3.1 per cent (3.4 per cent) over and above the earnings of a graduate who attended an LEA school, ceteris paribus . We also find considerable variation across different Independent schools in the size of the graduate earnings premium, especially for males, and show that in the case of males the premium increases with the level of school fees, but is not statistically related to measures of school–level average academic performance.  相似文献

This paper develops a model of media bias in which rational agents acquire all their news from the source that is most likely to confirm their prior beliefs. Despite only wishing to make the correct decision, agents act as if they enjoy receiving news that supports their preconceptions. By exclusively gathering information from a source biased towards his prior, there is little chance an agent will be persuaded to change his mind. Moreover, it is shown that even an unbiased agent prefers to receive biased news as it is unlikely to produce conflicting reports. The media caters to the informational demands of consumers and accordingly slants its reporting. It is shown that competition may not decrease bias, but may actually enhance it. Finally, even when it increases bias, competition may improve welfare by expanding the market for news.  相似文献

There is a rising tide of health care fraud in this country. And it is costing all of us upwards of $100 billion each year, adding to already skyrocketing medical costs. Many companies do not have adequate internal controls over their health care system. And even when they do, monitoring or auditing is lax. The authors explore the scope of these problems and offer practical advice on stemming the tide. © 2005 Wiley Periodicals, Inc.  相似文献

Federal and state laws require environmental cleanup that's often either not recognized or understated in financial statements. But now, the Sarbanes‐Oxley Act (SOX) requires management to certify financial statements and internal controls. This makes management criminally liable for proper environmental cleanup reporting! So how should you identify, estimate, and report cleanup liabilities? The authors of this article offer some guidance. © 2005 Wiley Periodicals, Inc.  相似文献
